Abstract
A system and method of using the system are provided for collecting and analyzing urine from an animal. A cage with a fluid pervious floor is provided for holding an animal. Urine from the animal flows through the cage floor into a hydrostatic column. An analyzing device is engaged with or positioned proximate to the column in position to analyze the urine entering the column. The column is structured to discharge a volume of liquid equivalent to the volume of urine that enters the column. The discharged liquid is received in a container which is located on a scale that weighs the received liquid. Data from the analyzing device and the scale is automatically stored by a data processing system. A rinse container with a liquid rinse is provided to rinse the column. Preferably the data processing system automatically controls valves to automatically rinse the column after each animal urination or after a predetermined period of time has elapsed.
